Welcome Jen!
I have found trust the hardest issue in my life. Do you work outside the home? If you don't, it's a great idea for you to get a job and begin to build confidence. That is part of the trust issue. You have to learn to trust yourself and your own judgment, before you will ever really be able to relax. You have to be able to tell yourself that even if things don't work out with this guy, you can make it. You need some life experiences of your own, without any manipulation or dependence.
